WP 34S RPN Scientific Calculator Beginners Guide Page 1 of 187 1 Draft 2.06821~ Firmware: 34S 3.1 2932 ~ ( www.conehead.org & cb1 at conehead dot org) Page 2 of 187 10 1 9 8 2 3 7 4 5 6 Figure 1 – Keyboard Navigation Summary Overview (1) The top line of keys can be used to quickly execute a program label when any of the labels A, B, C or D are defined within a program by the user. If these are not defined, then the primary function of each key will be sigma add, reciprocal, power or root respectively. Note that each of these functions is available elsewhere on the keyboard. (2) Enters a number. (3) The primary function of the XEQ key is to execute a function or program (4) These scroll keys are used to move up or down within a program or a catalogue list (5) The primary function of the EXIT key is a general escape or cancel button. Secondary functions are used to switch the calculator on/off. Yellow shift switches between upper and lower case when entering text and blue shift “SHOW” can be used to view any register (including the stack contents). (6) Primary function of this key is to run/stop a program. Secondary functions include inserting labels, or subroutine returns. (7) Backspace key, with secondary function used to clear x, clear program or clear sigma data. (8) Every Keys primary function is shown in white on the front face of the keys. Secondary functions are shown as yellow, blue or green requiring a prefix of these respective f, g or h keys. Keys are used when entering text characters – and these are shown as grey characters (shown at the bottom left of the key). For example the EEX key is pressed when entering the letter “L” (9) The CPX (complex) primary function is used as a prefix for commands that must execute in the complex domain. Pressing CPX before + for example would perform a complex math addition. Observe that the green secondary function of this key has an underline (MODE) which means that this key opens a catalogue of functions (in this case related to the calculator mode of operation). (10) The right arrow key is used as a prefix to force a conversion of whatever is in the X register. It can be used before H.d, H.MS, DEG, RAD, GRAD. It can also be used before the bases “2” and “8” (+/- key) and “10”, “16” (EEX key) to perform quick base conversions. Additionally this button is pressed to signify the use of indirect addressing mode. 2 Draft 2.06821~ Firmware: 34S 3.1 2932 ~ ( www.conehead.org & cb1 at conehead dot org) Page 3 of 187 WP 34S RPN Scientific Calculator Beginners Guide Front cover: WP 34S by Walter, Pauli, Marcus, Neil, Eric and many others, accompanied by a much loved HP 32E in the background 3 Draft 2.06821~ Firmware: 34S 3.1 2932 ~ ( www.conehead.org & cb1 at conehead dot org) Page 4 of 187 Dedicated to my wife who also helped me see the light 4 Draft 2.06821~ Firmware: 34S 3.1 2932 ~ ( www.conehead.org & cb1 at conehead dot org) Page 5 of 187 Index Index ........................................................................................................ 5 Table of Figures .......................................................................................... 9 Draft Release Change Details...................................................................... 10 If you ever find yourself in an unexpected mode? ......................................... 12 Who am I? ............................................................................................... 12 Introduction ............................................................................................. 13 Where this document fits in and the inevitable legal disclaimer .................... 15 Getting Started......................................................................................... 17 Switching On ......................................................................................... 17 Setting the LCD Display Contrast.............................................................. 18 Entering numbers................................................................................... 18 Changing the sign of the number ............................................................. 18 Clearing ................................................................................................ 18 Functions using one number .................................................................... 19 Functions using two numbers................................................................... 21 Chain calculations .................................................................................. 23 Setting the display format.......................................................................... 24 Scientific display notation -

The square root of a number, n, is that value when multiplied by itself equals n. 2 x 2 = 4 and = 2. Calculating the square root of the number is the inverse operation of squaring that number = n. The "√" symbol is called the "radical" symbol or "check mark." MS Word has the radical symbol, √, but we often use it with a line across the top. This is called the "vinculum" circa 12th century. The expression " (2)" is read as "root n", "radical n", or "the square root of n". The vinculum extends over the number to make it inclusive e.g. Most HP calculators have the square root key as a primary key as shown in Fig. 1 because it is used so much. Roots and Powers Numbers may be raised to any power (y, multiplied by itself x times) and the inverse operation, taking the root, may be expressed as shown below.

  • RPN Calculators for Linux
    LinuxFocus article number 319 http://linuxfocus.org RPN calculators for Linux by Guido Socher (homepage) About the author: Abstract: My first RPN calculator was a HP15c and it was RPN stands for Reverse Polish Notation. Reverse Polish Notation was love at first sight. developed in 1920 by Jan Lukasiewicz as a way to write a mathematical expression without using parentheses and brackets. It takes a few minutes to learn RPN but you will soon see that this entry method is superior to the algbraic format. _________________ _________________ _________________ Introduction RPN pocket calculators became popolar with the HP calculators. HP used this entry method already for it's first calculator in 1968. If you search the internet you will find that there is a whole fan club behind those HP calculators. I have made a number of very good links available at the end of this article. Most of those HP calculators are today collectors items and sell now for much more than their original price. In this article will present some of the RPN desktop calculators available for Linux. We will not only look at the HP emulators which are available but also other RPN calculators which are totally independent of HP. What is RPN? Why RPN? RPN calculators use a stack and all mathematical operations are executed immediately on the lower level of the stack. The stack is used as a memory to save results which you need to further evaluate your formula. Therefore you do not need any brackets on an RPN calculator. You first enter the numbers, push them up the stack, and then you say what you want to do with those numbers.

  • Rplsh: an Interactive Shell for Stack-Based Numerical Computation
    RPLsh: An Interactive Shell for Stack-based Numerical Computation Kevin P. Rauch Dept. of Astronomy, University of Maryland, College Park, MD 20742 Abstract. RPL shell1, or RPLsh, is an interactive numerical shell designed to combine the convenience of a hand-held calculator with the computa- tional power and advanced numerical functionality of a workstation. The user interface is modeled after stack-based scientific calculators such as those made by Hewlett-Packard (RPL2 is the name of the Forth-like pro- gramming language used in the HP 48 series), but includes many features not found in hand-held devices, such as a multi-threaded kernel with job control, integrated extended precision arithmetic, a large library of spe- cial functions, and a dynamic, resizable window display. As a native C/C++ application, it is over 1000 times faster than HP 48 emulators (e.g., Emu483) in simple benchmarks; for extended precision numerical analysis, its performance can exceed that of Mathematica R by similar amounts. Current development focuses on interactive user functionality, with comprehensive programming/debugging support to follow. 1. Introduction The notion of progress in computer hardware has always been closely tied to the speed and sophistication with which numerical calculations can be performed. While the continuation of Moore's Law has resulted in hand-held devices more powerful than the 30 ton ENIAC machine, there is a growing gap between the speed and capabilities of hand-held scientific calculators as compared to desk- top workstations|the result of both market forces (pricing pressure) and phys- ical limitations (keyboard/screen size). Numerical analysis packages such as Mathematica or IDL, by contrast, are oriented towards script or command line processing, and lack the interactive amenities found in a traditional calculator.

  • HP-45 Owner's Handbook
    Hewlett-Packard's interest in computation evolved as a natural extension of our traditional involvement in measurement problem solving. At an early date, HP recognized the growing need for a family of computational products designed to work easily and effectively with scientific instruments. In 1966 we introduced the first digital minicomputer specifically designed to meet this need. Soon after, we followed up with our first programmable calculator. From these beginnings, HP has now become an acknowledged leader in the field of computational problem solving. More than 20,000 HP programmable calculators and digital computers are at work in a wide range of applications in science, industry, education, medicine, and business. Their ef­ fectiveness is further enhanced by a complete line of accessory devices, ranging from digital tape and disc drives to card and tape readers, printers, and plotters. Lately we've coupled our experience in scientific problem solving and computational technology to bring you new dimensions in personal computation-the HP-80 Business Pocket Calculator for solving problems in business and finance, the HP-35 Scientific Pocket Calculator for engineering/ scientific applications, and now the HP-45 Advanced Scientific Pocket Calculator whose expanded functional capability and multiple storage registers allow complex problems to be handled with unprecedented ease. <CI HEWLETT· PACKARD COMP"NY, 1973 Attention Please! To give you more computing power, your HP-45 works in a con­ sistent and natural way that may be slightly different from previous calculators you have operated. Even though your new HP-45 is simple to operate, and you can start solving problems immediately by following the Quick Reference Guide accompanying the HP-45, you will find it worthwhile to read this handbook.

  • HP Calculator Programming Richard J
    HP Calculator Programming Richard J. Nelson Introduction Do you use an HP calculator that has a programming capability, and do you actually use it? Of the 24 models, see Table 1 below, 23 are on the HP website 13, or 54.2%, are programmable. If the Home and Office machines are omitted, the numbers are: 17 models, and 13 or 76.5%, are programmable. What does this mean? A program is a sequence of instructions (functions and/or data) that are keyed (or loaded) into the calculator’s memory that will solve a particular problem or provide specific information. A program capability also includes special instructions that provide prompting for inputs and labeling for outputs. Another aspect of a program capability is the ability to perform decision logic so the particular parts of a program may be changed depending on the results of previous instructions. This capability provides “intelligence” to the program. The program capability of the 10 current models ranges from very simple such as the HP-12C to very complex (and very powerful) such as the HP 50g. Older HP calculators such as the HP-71B or HP-75C used a computer like programming language called BASIC. The HP-12C and HP-15C programing language is an RPN FOCAL(1) like language, and the HP 50g uses an RPL programming language. The algebraic calculators use what may be called an Aplet programming language.

  • RPN Calculates Faster. Get Accurate Results in Less Time with the HP 12C
    RPN calculates faster. Get accurate results in less time with the HP 12c. WHAT IS RPN? RPN (Reverse Polish Notation) is a mathematical notation that allows users to solve problems by mimicking how they learned to do math on paper. The operators (+,–,x,÷) are placed after the arguments (for example, 3+4 becomes 3 {ENTER} 4 +) allowing users to stack number sequences and operations, working from the bottom up. RPN eliminates the need for parentheses in complex calculations and reduces keystrokes, making problem solving quicker and more effi cient. T T Pressing an operator key (+ - x ÷) always collapses the bottom two rows of the stack. Z Z Y 3 x Y X 4 + X 7 Solving a Basic TVM Problem PV= 50 What is the Future Value of $50 invested today at r = 3% TVM Formula Formula with inputs N 5 3% interest for 5 years? N = 5 FV = PV x (1 + r) FV = 50 x (1 + .03) FV = ? Traditional Calculation Methods You might think all traditional calculators operate the same way, but there are actually two common operating modes, which require users to input formulas diff erently. Chain Algebraic Mode: Chain Mode calculates from left to right without following the Order of Operations. 50 x (1 + .03^5) = Algebraic Mode: Algebraic Mode follows the Order of Operations (Please Excuse My Dear Aunt Sally). 50 x (1 + .03)^5 = If you’re not sure which mode your calculator uses, you likely add extra parentheses to Mode Unknown: avoid potential errors, making calculations complicated and time consuming. 50 x ((1 + .03)^5)= RPN Method Final Answer: $57.96 RPN breaks equations into simpler components, making them easier to solve.
